But let’s go back in time 10 or 15 years. Back then people were buying stuff that was around 12 to 14% efficient. Now people are buying stuff that is 19% to 22% efficient. That’s a big ass jump in efficiency over a decade.

The tech is rolling out, it just takes time to move stuff from R&D to manufacturing at scale and at a reasonable cost.

There is often a long lead time between the breakthrough science, new industrial applications, and when you can buy something at HomeDepot. It’s always going to be that way.

Oh yeah I was specifically talking about all these new technologies, not just incremental improvements on the existing ones. Hybrid organic cells have been promised for a long time and it's not just a question of scaling etc., but that they have had serious issues that have so far meant that they were a complete non-starter for any actual real-world use. I didn't look into this any further so I don't know of Longi solved the stability problem, though, so it may be that they're finally actually ready to even start leaving the lab
